As described above, the rack bracket 12 has the flange portion 12a around it. That is, when the rack bracket 12 is attached to the side panel 41, the flange portion 12 a of the second portion 12 c is fixed to the panel 41 with the bolts and nuts 42. At this time, a cap nut is used on the inner side of the flange portion 12a facing the inner side of the luggage shelf 10 so as not to damage the hand of the passenger or the luggage. The side panel 41 is also integrally provided with a hook 43 for collecting various harnesses.

  After the upper panel 36 is attached, the side panel 41 to which the rack bracket 12 is attached as described above is attached. At this time, the bent upper end extending to the ceiling 1a of the side panel 41 is inserted into the clip 39 of the upper panel 36 described above, and the flange portion 12a in the first portion 12b of the rack bracket 12 is connected to the bolt 21 and the nut 22 described above. It fixes to the ceiling 1a using. Since the plurality of flange portions 12a of the rack bracket 12 are provided on both the front and rear sides along the traveling direction of the vehicle, both sides of the rack bracket 12 are screwed using the flange portions 12a. .

  Then, the cooler duct 20 is completed by attaching the lower panel 32 to the curtain rail 31 described above. As described above, since the bolt 33 is inserted in the slot 34 in advance in the curtain rail 31, the end of the lower panel 32 is overlapped with the end of the curtain rail 31, and a nut 44 is attached to the bolt 33. By attaching, the lower panel 32 can be fixed to the curtain rail 31.

  A hinge portion 45 is provided near the position where the lower panel 32 is attached to the curtain rail 31. The hinge portion 45 can rotate the lower panel 32 downward with the lower panel 32 attached to the curtain rail 31 to open the lower surface side of the cooler duct 20.

  A service unit 50 as shown in FIG. 5 is attached to the lower panel 32. The service unit 50 includes two reading lamps 51 and 52 that can adjust the irradiation direction of the illumination light, two switches 53 and 54 that turn these reading lamps on and off, and an air blowing mechanism 55 that is connected to the cooler duct 20. Have. That is, by enabling the lower panel 32 to be opened by the hinge portion 45 described above, maintenance of the service unit 50, inspection of the harness, and the like are possible.

  As shown in an enlarged view in FIG. 3, an end member 32 a made of a resin material having a hollow V-shaped cross section is attached to the open side end of the lower panel 32. The service unit 50 described above is fixed to the terminal member 32a with screws 46. The terminal member 32a has a slot 32b into which a hollow core member 47 made of aluminum is inserted. The core member 47 is also formed in a hollow structure having rails 47a through which the heads of a plurality of bolts 48 are inserted, like the core member 14 described above.

  That is, when closing the lower panel 32, the terminal member 32a is brought into contact with the outer surface of the panel bracket 12, and at the same time, the bolt 48 is slid along the rail 47a and inserted into the hole provided in the flange portion 12a. The cap nut 49 is fastened to the bolt 48 on the back side of 12a. Conversely, when the lower panel 32 is opened for maintenance, the cap nut 49 is removed and the lower panel 32 is rotated about the hinge portion 45.

  After attaching the lower panel 32 of the cooler duct 20, the rack panel 16 is attached to the third portion 12 d of the rack bracket 12. In this case, the rack panel 16 in which the two core members 14 are previously inserted and arranged in the slots 16a is brought into contact with the lower surface of the third portion 12d of the rack bracket 12, and at the same time, provided on the flange portion 12a of the third portion 12d. The bolt 23 is inserted into the hole. Then, the cap nut 61 is attached from the inside of the flange portion 12 a to fix the rack panel 16 to the flange portion 12 a of the rack bracket 12.

  Thus, the connection strength can be increased by fixing the aluminum core member 14 incorporated in the resin rack panel 16 and the rack bracket 12 made of aluminum die-casting. Also in this case, a cap nut 61 is disposed on the inner side of the flange portion 12a of the bracket in order not to provide a projection that causes a catch on the inner side of the luggage shelf 10.

  As shown in FIG. 4, an outer skin 70 is attached to the rack panel 16, and the outer skin 70 is also formed of the same material as the rack panel 16. Reference numeral 71 denotes a cover member that covers the boundary of the rack panel 16 divided into a plurality of parts in the vehicle traveling direction.

  Finally, a rack end 62 that covers the vehicle width direction inner end of the third portion 12d of the rack bracket 12 and the vehicle width direction inner end of the rack panel 16 is attached. The rack end 62 has a slot 64 extending in the vehicle direction through which the head of the bolt 63 is inserted so as not to rotate. A flange portion 12a extends in the substantially vertical direction at the end of the rack bracket 12, and the cap end 65 is fastened to the end of the rack bracket 12 by fastening a cap nut 65 through a bolt 63 to the hole of the flange portion 12a. Fixed to the part. Since the rack end 62 is located at the end of the luggage shelf 10 in the vehicle width direction, there is a high possibility that a passenger walking in the passage touches this part. For this reason, the rack end 62 has a curved shape, and the upper end 62 a thereof is rounded so as to cover the end of the flange portion 12 a of the rack bracket 12.

  As described above, the luggage rack 10 of the present embodiment uses a single-layer PVC as the bottom plate member, so that the appearance from the seat and the passage can be improved, and the merchantability can be improved. Further, when PVC is used, the bottom plate member can be made transparent, so that it can be easily recognized that the luggage remains, and misplacement of the luggage can be prevented.

  Further, by using relatively inexpensive PVC for the bottom plate member that occupies most of the luggage rack 10 as in the present embodiment, in addition to the above-described improvement in merchantability, the material cost can be reduced, and accordingly, manufacturing Cost can be reduced. In particular, the use of PVC may cause a decrease in strength. However, since the aluminum core member 14 extending in the vehicle direction is incorporated in the rack panel 16, sufficient mechanical strength can be achieved. Further, since the core member 14 is inserted and arranged in the slot 16a in advance before the rack panel 16 is attached, the number of assembling steps does not increase even if the core member 14 is provided, and the manufacturing cost is affected. There is no effect.

  Furthermore, in addition to being easy to process, PVC is excellent in recyclability and can reduce adverse effects on the natural environment.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
